                                        Measurement of Mass (Weight)



               In Class 1, we used some non-standard units such as marbles, pebbles,

               etc.,  to  weigh  different  objects.  Here  we  will  learn  standard  units  of
               weights.

               The gram and the kilogram are standard units of weight.

               Gram


               We  use  grams  to  weigh  lighter  objects.  In  the  short  form,  gram  is
               written as g. A gram is a smaller unit of mass (weight).
